Let the shorter parallel line be x
So the longer one will be x+4
area of trapezium= (x+x+4)(8)/2
248=(2x+4)(4)
62=2x+4
2x=58m
x=29m
x+4=(29+4)m=33m
So the longer one will be x+4
area of trapezium= (x+x+4)(8)/2
248=(2x+4)(4)
62=2x+4
2x=58m
x=29m
x+4=(29+4)m=33m

You have just find out 1 side mthat is a=33 m . To find out b (the second side) 33-4=29m.
